sevisehda: I said upwards of 40 lbs, I agree that its unlikely someone will be able to carry 8 stacked bins. I do think the angle helps the robot going up the ramp, its hard to tell though. Regradless, most robots will be able to push most other robots off the top of the ramp. I doubt any robot can withstand the force of 2 other robots trying to push it off the HDPE. Only time will tell.

HDPE DOES have traction!
Did you guys do ANY experimentation? We have materials that get better coefficient of friction on HDPE than on Carpet!
Neoprene for example... it is capable of getting a mu of upwards of 3 on the HDPE. Now imagine, a robot that puts 400+ lbs of normal force on a coeff of 3. (let me do the math for you) it will take 1200lbs of linear force to move them! You call that "easy to push"?
Can your robot push with that much force? Even with 100 bins you can't do that...
There will be numerous robots that can stick to the ramp, and withstand an attack from multiple other robots.
I think your assumptions about the game... AND about the laws of physics are flawed. I think this game will surprise you, in BIG ways.
